Yes this confused me a lot man!
Anyhow, I just studied bio in last 2 days before CIE.
I answered a bit amateurly that " Human breathe for maintaining the gaseous exchange while plants respire to maintain photosynthesis or diffusion of Co2 and O2 in out." and a couple of explainations with it. Though, I don't know if it was the correct answer.

Well I wrote since the human require oxygen for the cell they breathe, during which they release carbon dioxide which is a useless gas from respiration but in case of plants they require carbondioxide, so instead of breathing they perform the process of photosynthesis to provide energy to it's cell! .-.
I hope this one's okay too.
